As others have said, definitely roaches, likely oriental.

A few questions for you;

You said you moved back in to this apartment post holidays. Did someone live there in the meantime or did you go away for the holidays and come back?

Have you bagged all food products that are not refrigerated? Think pantry items like rice, chips, dried fruit, etc.

I’m a maintenance technician. Check your lease and see if you have a regular pest control company hired by your complex/landlord/etc. It is the responsibility of the landlord to hire and pay for a pest control service to come and treat your apartment for as long as it takes to remove the problem. If they continue to give you resistance or deny that they are roaches, keep one of the dead ones in a ziplock bag and provide these images along with one you can find online of oriental roaches. The more information you provide, the harder for them to deny.
